Letters Patent No. 98,871, dated January 18, 1870.

IMPRGVEMENT IN FELTING-MACHINES- The Schedule referred to in theseLetters Patent and making part of the same.

To whom it mag/concern.-

Be it known that I, Fannnnion S. JENNINGS, of Danbury, in the county ofFairfield, and State of Connecticut, have invented certain Improvementsin Felting or Eching-Machines, of which the following is aspecification.

Nature and Objects of my Invention.

The first part of myiinvention consists in having four rollers, more orless, so arranged as to form a chamber between them, and in having therollers all roll one way, so as to keep the goods being felted orfulled, continually rolling between the rollers, and in having the upperroll or rollers att-ached to a hinged frame, capable of being raised bya treadle worked by the foot, or other means, at any time during theprogress ol' the work, and admit the operator to inspect the goods andgive the proper attention, or to remove them when necessary.

' The second part consists in having a jiggcr, reciprocating betweenythe upper and lower rollers, and coming in contact with the goods in themachine, being felted or fulled, on the front and back partealternately, and giving the goods a rolling motion, so that while thegoods are rolling between the rollers, the jigger is brought in contactwith the goods at a different point at every recprocation, which willgive uniformity of action upon the goods throughout the entire surfacebrought in contact with the rollers and jigger.

The third part of theinvention consists in changing the continuousrevolving motion of the rollers, to an intermitting vibratory motion,with the means of adjusting the vibratory motion ofthe rollers, withoutdisturbing the movements of th jigger which reciprocates between therollers.

Description of thc Accompanying Drawings.

Figure l is .a plan view of the machine containing my invention;

Figure 2 is a side view of the same; and

Figure 3 is a sectional view of all the parts, when out longitudinallyand vertically through the centre.

General Description;

A, in the drawings, represents the supporting-frame,

made in any convenient manner or form for the purpose.

A is a frame, resting on the supporting-frame, and

contains and supports the driving-shaft ofthe ma-v chine, and thenecessary gear-wheels, pulleys, and

bands, to give motion to the operating-rollers.

B is an inclined table and vat, sustained by frame A. Transvcrsely tothe frame A', and within the vat B, are arranged two ormoreylongitudinally-corrugated or iluted rollers, C O, andfimmediatelyabove rollers O C are two or more similar -rollers, C C', arranged inframe A, which is hinged to frame A at o.

A continuous revolving motion, in the same direction, is given theserollers, by means of belt d', from driving-shaft D, to pulley c', andbelt c to pulley a, on the shaft of which is a gear-wheel, b, whichgears into-pinions b' b b b', on the rollers (l O and G C.

When an iutermitting vibratory motion is wanted upon the rollers, theband c' is removed from the pulleys, and connecting-rod is placed uponcrank or wrist-pins in pulleysl a and a, which will, as pulley a.continues to revolve, give the pulley a an interinitting vibratorymotion, which is transmitted through gear- Wheels b and b b b b to therollers C C and C C.

The crank-pin or pulley a" is attached to a slide, which allows thecrank-piu to be adjusted to any given distance from the centre of pulleya, which will give a greater or less vibration to the rollers, as may bedesired, when the slide having the crank-pin attached is adjusted forsuch change.

Frame A." is hinged toframe A' at o, which allows frame lA to be raised,so that the goods or cloth J can readily be placed between theoperating-rollers, and, when fully 'acted upon, to be removed from themachine.

In order to have a convenient means o f4 raising the frame A,foot-treadle F, having band g goingover pulley H, and around the lowerend of arm h, that is hinged, at i, to the frame A, is employed, whicharrangement is always sure to raise theframe whenever the operators footis borne upon the treadle F.

Upon the driving-shaft D is a pulley, G.

Around said pulley G, and over pulley D', is a driving-belt, d, givingmotion to shaft Daud crank-wheels D" D", having crank-pins d d' andconnecting-rods d" d", that connect with. and give a reciprocatingmotion to jigger E, which has two cross-bars, one of which is uponeither side of the goods J to be acted upon, as seen in fig. 3.

Jigger E is keptin its line of reciprocation by means of its sidesworkin g in grooves in thesides of frame A.

J is the roll of goods to be feltedand is acted upon by the rollers andthe jigger.

Vat B, in which rollers G G revolve, isfilled with water or size, andcan be kept, while the operation of felting or fulling is going on, fullof water or size, even to the submerging ofthe rollers, if necessary,and the water or size can be kept at any temperature desired, byapplying steam through a steam-pipe to the vat.

By this arrangement of devices, asabove described, double the amount ofwork can be done on the goods to be felted or fulled in `a given time,than by any known method heretofore used, for the reason that the.corrugated rollers are simultaneously operating on four sides, 'or atfour different points, while the jigger is alternately giving its blowsupon opposite sides of the goods, attacking nearly the entire surface ofthe goods at every instant of time, and thus effect the object ofproducing felted goods for hatbodies or other purposes, in a less spaceof time, with less injury to the fibre, and at a less cost.

1n the process of felting or shrinking the lgoods to the proper size,lche intermitting vibratory motion is first used upon the goods, as bythis motion the fabric is caused to shrink faster than by a continuousrotary motion, while a continuous rotary motion upon the fabric, whichmay be a roll of hats or other goods, is apt to set, or to ceaseshrinking or felting before the fabric comes to the proper size; butafter the vibra- .tory motion of the rollers has been applied asulicient time, then the continuous 'revolving or rotary motion is giventhe rollers, which will give a bard, firm, and smooth felt, and thefabric or goods are ready for the next process.

Having thus fully described my invention,

What I claim, and desire to secure by Letters Patent, is-

1. The revolving longitudinally-duted or corrugated rollers C 0 and CC', when constructed and arranged to operated in the` manner and for thepurposes substantially as described.

2. The reciprocating jig'ger E, constructed with the two cross-bars, andoperating in the manner and for the purpose substantially as described.

3. The revolving rollers C C and C C', in combination with thereciprocating jigger E, all constructed and'arranged to operate togetherin the manner and for the purpose substantially as specified.

4. The pulley a', connecting-rod I, pulley a, with sliding crank-pin,gear-wheels b b' b b b', in combination `with the rollers O C and C C',when arranged to operate in the manner and for the purpose substantiallyas described.

5. The pulley a connecting-rod I, pulley a", with sliding `crank-pin,gear-wheels b b' b b b', rollers G C and OC, in combination with thereciprocating jiggerv E, when arranged to operate in the manner' and forthe purpose substantially as described.
